is'in the form of a metallic diameter of the cylinder, A correspondinglyshaped cover 2 is adapted tofit over the opening 1?). The cover 2isprovided with a cenvtral boss portion 2a and reinforcing ribs 25and2c; The cover-is held in position by means of 'a clamp member 3. Theclamp member 3 comprisesa central bossportion 3a, and oppositelyextending arms 3?) which are bent at their outer ends substantially atrightangles with the central portions and parallel with the axis of theboss 3a and at their extremeends form laterally extending hookportions30. The hookportions 3c'are adapted to 'engagethe lugs 10 formingintegral parts of the casing 1 and positioned substantially in themajoraxis of the opening 1?). A clamping bolt 4 is adapted to be screwedthroughthe bossBa into engagement with the boss 2a of the cover 2,thereby forcing the cover against the casing. A gasket 18 is positionedbetween the cover and the casing for "obtaining a tight joint. The solidend 10 of the casingis provided with threaded open-i ings to receiverthe inlet and outlet pipes'I and Ozwhich. are preferablyscrewed into theend 1a and secured in locked position by means of the nuts 19 and 20'.The inlet pipe I extends within the casing 1 and forms a sleeve- 'mentwith the axis of the boss 1d. The sus. pension loops 9 are madepreferably of metallic -strips and form at their upper end a -hookportion 9a adapted to engage the suspension rod 7, a central,cylindrical portion 7 '5 for supporting the one end of the: diffusingcylinder The diflusing cylinder 5 includesa long, laterally arcuatestrip or shield 5a having at its one end a cylindrical portion 5?)adapted to be; received by .the sleeve 2'. The end opposite thecylindrical portion 5?) is secured to a circular cap 50. Extendinglengthwise between the cap and the cylindrical portion 56 is an angularbaflle'5cl. Thebaffle 5d is supported in parallel spaced relation withthe shield with the side portions extending downwardly. A tube 56 formedof wire gauze is positioned over the shield 5a and the baffie member 5dand extends between the cap tic-and the cylindrical portion 56.

. The filter cylinder 6 is connected with the outlet 0 by means of asleeve 6a which is "adapted to slip into the inner end of the outformingthe filtering medium of the device.

The fabric 6 is held in position by means "ofa plurality of hoops 6gwhich-are prefresi-lie'nt, split rings.

erably in the form of The filter cylinder 6. i-s 'suspended :by means ofthe suspension loops 9 from a suspension rod 7. The latter is preferablyscrewed into a boss lcZ-extending inwardly from the end member 1a 'nearthe periphery thereof, and is supported near its other end by means -ofthe depending ear 16, which is provided with a suitable aperturesubstantially in aline- 9b of adiameter sulficient to-accomm'oda te'jthe filtering cylinder6=and a downwardly depending eye portion 90. Thesuspension loops Sfa re positioned closeto the ends of the 'filterincylinder 6 and'support the latter somewhat above the center of thecasing 1 in alinement with the outlet pipe 0; A second suspensionrod 8is supported in the eye portions 90 of the suspension loops 9. A secondpair of suspensionloops 10, which form an upper hook portion 10a have asubstantially cir- :cular portion 10?) adapted to encircle the diffusingcylinder 5 and are suspended by'rneans of the hook portion 10a from thesuspension rod Sand supportthe diffusing cylinder 5 in 1-co"rrect;aline1nent withthe inlet pipe I below "the filter cylinder6.Axial displacement of the 'di-lfusing cylinder 5 is preventedby-m'eanslows: The fluid, such as illuminatin of the lock bar 11 which extendsacross the cap member 50 and is supported at its end in the keepers 12,secured to the inner side of the casing 1 in line with the horizontalaxis of the cap 50., The filter cylinder 6 is forced by the fluidpressure within the casing l in a direction against the inner surface ofthe end member 1a and in order to prevent leakage of the fluid asuitable washer 21 is positioned between the cap '6?) and the innersurface of the end member 1a around the inner end'portion of the outletpipe 0.

A handhole 1 is provided in the lower side of the casing'l adjacent theopening 1?) therein. The handhole 17 is sealed by means of a cover 13which is held in position by means of the handholdclamp bolt15. Thelatter is creWably-supported in a clamp member 14 extending across thecover 13 and supported on the studs 16, as clearly shown in Fig. l ofthe drawings. A gasket 17 is provided between the cover 13 and themargin of the opening 1 for preventing leakage of fluid through theoints.

Theoperation of my fluid filter is as fol- 0 gas, entors the diffusingcylinder 5 throu h the inlet I and passes out through the'side t ereofat reduced velocity, following the direction lb tl F 2 O I t lllCLluuLGCy 1e arrows in. 1 win o the disposition of the arcuate member 5a and theangular baffle member 5d, the fluid is directed toward the lower,central side portions of theca-s-in'g 1, and is prevented from flowingagainst the bottom of the casing by means of the baffle 5d, and fromtaking :an

upward direction by meansof the shield 5a.

The function of the wire gauze :56 is to more or less evenly diffuse thefluid entering the cylinder over its entire length so that the fluidinzpassing between thediflusin'g cylinderand the filtering cylinderflows more or less in a vertical direction, thereby zavoidingiaxialniovement within the casingl, with the' resu lt that whirls a'nd eddiesare reduced as faras possible.

'Oiving'to the greatly reduced velocity of the fluid passing from thediffusing cylinder the .greater part of the impurities brought into thediffusing cylinder will be released, forming :a heap below-the'di'fl'using chamber,

as indicated in dotted lines in Fig. 3. Owing to thedisposition of theangular baffle 5(l,'the pile ismore or less protected from the flow'of'the fluid and will not be drawn up thereby-7.

The fabric 6f on the filter cylinder prevents'sthe passage "of any ofthe :finer and lighter particles of deleterious-matter still containedin the fluid "from entering the cylinder. 6 and passingout through the:outlet pipeO.

. J Where .it is desired to remove the ;precipi tated deleterious matterfrom the cylinder,

the hand'hole 1 isopened by removing the cover 13. This is readilyaccomplished by loosening the clamping bolt 15 and removing the clamp 14from the stud 16. One deposit can then be easily scraped out. Y

As occasion demands the filter cylinder 6 is removed from the casing 1by withdrawing it from the suspension loop 9. This, of course, can bereadily accomplished as the sleeve portion 6a fits slidably within theinner end of the outlet 0.

The diffusing cylinder 5 may also be readily removed by raising thelocking bar l1 and f withdrawing axially from the sleeve 2', and thesuspension loops 10.

It is obvious that the cover 2 of the casing is removed by loosening theclamping bolt 4 and revolving the clamp member 3 anticlockwise until thehook portions 30 thereof clear the lugs 10. The clamp and cover can thenbe removed. As it is unnecessary to have access to the inner end of thecylinder for removing the parts contained therein, accessibility of thatpart is not essential and the inlet and outlet pipes may be entirelyconcealed or buried.

Though I have shown and described a particular construction, combinationand arrangement of parts and portions, I do not wish to be limitedtothis particular construction, combination'and arrangement, but desireto include in the scope of my invention the construction, combinationand arrangement substantially as set forth in the appended claims.
